FEATURES 30 | 866-660-8864 | fax 503-296-2529 | www.senvainc.com EM Series Rogowski CVT TM Sensors 1% total system accuracy (meter & CVT) For use with Pulse and Protocol Versions of the EM Series Meter Flexible Split-core Rogowski CVT TM Sensors Monitor loads from 30-6000A & 90-600V DESCRIPTION The Current/Voltage Transducer TM (CVT TM ) measures both voltage and current, communicating the data digitally to the meter via plug-in low voltage connections. This allows the meter to remain a low-voltage device. Each CVT TM uses digital communication with the meter for superior noise immunity. The CVTs TM are individually calibrated and measurement accuracy is independent of the transducer. To complement the CVT TM , our metering platform offers two meter options (EM-PULSE & EM-RS485) which are small enough to fit in the palm of your hand, yet powerful enough to self-configure during installation, removing all manual configuration. Virtually a plug and play BACnet meter! Intelligent CVTs TM boast numerous benefits: ▪ Digitally calibrated CVTs TM are extremely accurate ▪ The accuracy is as high as a calibrated system, yet different CVTs TM can be changed from meter to meter while maintaining accuracy. A big advantage for auditing, since meter is not size specific. ▪ Plug and play installation— individual CVTs TM are digitally recognized by the meter and outputs are automatically scaled—no user set up is required. ▪ Digital communication offers superior noise immunity compared to traditional induced low- signal Rogowskis ▪ All the high voltage connections are at the CVT TM ▪ Rogowski CVTs TM are available in 4 sizes from 9” to 36” in circumference and include several rating options from 300A to 6000A and are universally rated for 90-600V Split-core Rogowski CVT TM ▪ Easiest in the industry to install ▪ Senses both voltage & current ▪ High accuracy...digitally calibrated; interchangeable ▪ Available in multiple sizes & ratings to meet any project requirements Flexible split-core CVT TM sensors are easy to install and more accurate than traditional CTs APPLICATIONS ▪ Energy Management and performance contracting ▪ Monitoring for commercial tenants ▪Activity-based costing in commercial and industrial facilities ▪ Real-time power monitoring ▪ Load shedding ▪ Audits/temporary monitoring ▪Distributed generation 7 year limited warranty PROUDLY MADE IN USAHigher Reliability, Faster Installation, Superior Accuracy | Sense the difference | 31 ENERGY MONITORING EM Series SPECIFICATIONS PerformanceAccuracy 1% System Accuracy (Includes Meter & CVTs) for V, A, KW, kVAR, KVA Current/Voltage Transducer TM Small Rope Circumference Medium Rope Circumference Large Rope Circumference Grande Rope Circumference 9” 15” 24” 36” 300A Operating Range (1) 800A Operating Range (1) 1500A Operating Range (1) 2400A Operating Range (1) 6000A Operating Range (1) +/-1% 30-300A (+/-3% >10A) +/-1% 30-800A (+/-3% >10A) +/-1% 30-1500A (+/-3% >10A) +/-1% 50-2400A (+/-3% >15A) +/-1% 120-6000A (+/-3% >40A) Operating Environment Temperature-4 to 140 o F (-20 to 60 o C) Humidity0-95% non-condensing Meter Enclosure MaterialPolycarbonate/ABS Dimensions4.1”h x 1.8”w x 0.9”d CVT TM Enclosure MaterialPolycarbonate/ABS Enclosure Dimensions3.5”h x 1.6”w x 0.8”d Fuse specifications (see application note) Fuse type 1/2 Amp, 600VAC slow blow, 200kA AC Interrupting rating Dimensions4.1”h x 1.8”w x 0.9”d (1) Accuracy based on reading, not full scale.

Senva’s unique architecture keeps the high voltage connections contained within the CVT enclosure and in consideration to the tap rule Senva does not ship EM Series meters with more than 10 feet of voltage reference wire on any CVT. If your voltage reference must be longer than 10 feet, proper use of over current protection is required (i.e. appropriate fusing or circuit breakers.)
